Data sheet:
RS232 <> 20mA interface, Industry
Serial interface - connect with galvanic isolation
The Interface connects devices equipped with an RS232 interface to active or passive 20mA components. The built-in galvanic isolation ensures uninterrupted transmission in industrial environments.
Properties
Interfaces:
- 1 x RS232
- 9-pin Sub-D plug with PC pin assignments
- 1x 20mA
- 9-pin Sub-D plug
- Alternate designations: Current loop, TTY, line current interface
- Galvanic isolation between the ports
- Isolation voltage 1kV DC
Management and Connectivity:
- Active/Passive mode can be set individually for both loops
- No re-configuration of transmission parameters required
Power supply:
- External
- 12V-24V AC/DC via plug-in screw terminal
- Galvanically isolated power connection
